Abstract
The invention relates to a mono-substituted phosphinic acid and to the use thereof as a regulator in radical polymerization. Such regulators do not result in the formation of poorly soluble salts, and in addition, the polymers produced with the regulators according to the invention are characterized by a uniform polymerization degree having a narrow size distribution. In addition, the invention relates to a method for producing such mono-substituted phosphinic acids.
